I IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 167,756, datedSeptember 14, 1875; application filed September 3, 1875.

To all whom it may concern Be it known that I, IRVIN FREEMAN, of CorpusChristi, in the county of Nueces and 7 State of Texas, have invented anew and Improved Plow; and I do hereby declare that following is a full,clear, and exact description of the same, reference being had to theaccompanying drawing, forming a part of this specification, in which-Figure 1 is a side elevation, partly in section; Fig. 2, a bottom viewof share and moldboard Fig. 3, a detail view of shovel-plow.

Theinvention is an improvement in the class of plows whose shares orshovels are secured by means of a hook-rod passing through the beam. Theimprovement relates particularly to the construction and arrangement ofparts, whereby the mold-board and share are locked together, and theskeleton or standard secured to the beam by means of such hook-rod, allas hereinafter described. 4 r

A represents the beam, B the skeleton, O the share, and D themold-board, of a plow. The moldboard has a rigid subjacent part orattachment, D, projecting below the lower end, and provided with theslot d. d is a re cess in the upper end of part D to receive the lip I)of frame, in order to preventthe moldboard from moving upwardly, while dis a lip of mold-board that fits into a recess, 0, of share. The sharehas also a subjacent part or attachment, 0, that fits into slot 61 andin which is made a hole, 0 to receive the hook e of the long rod E. Thelatter extends up obliquely under the mold-board D, through the skeletonB at b 11 and also through the rear end of beam, so as to receive on itsthreaded end the lever-nut F. The mold-board being thus jointed at b dto the frame, and at c d to the share, the hook e is placed in the hole0 and thelever-nut turned one or more times to'secure the parts firmlytogether, while the rod E also serves as a re-enforcementto the whole.The arrangement of the hook-rod to pass through the rear portion of theskeleton B enables me to dispense with the bolt ordinarily employed toclamp or secure a skeleton to the rear end of a plow-beam. Thetop-slotted lug Gr, having head g, may be placed through a slot of ton,and securing it to the beam, in the man ner specified.
